Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done detailed explanation.

See also Fig. 2, the flow chart of access processing method in the embodiment of the invention, this method is applied to be communicated with in the communication system of access network based on IP, comprises step:

Step S21: receive the access request that subscriber equipment is initiated in the prohibited area;

Step S22: judge whether said subscriber equipment exists urgency traffic, if, execution in step S23, otherwise execution in step S25;

Step S23: accept said access request;

Step S24: keep the resource that urgency traffic uses;

Step S25: refusal inserts request.

Optional, said method also comprises: after the resource that keeps the urgency traffic use, discharge the resource that regular traffic uses.

Optional, said access request is tracing section updating request or Routing Area Update request.

In IP-CAN network (IP is communicated with access network); The network side network element is received subscriber equipment (User Equipment; UE) behind the access request message, forbid or roam and forbid that then the network side network element is initiated the network side resource release flow if find user's business in this zone; The resource that the regular traffic that the user is set up uses discharges, and keeps the related resource that urgency traffic uses.That is to say that initiate to insert request when subscriber equipment, the network side network element is after prohibited area receives said access request; Judge whether said subscriber equipment exists business to forbid or roam and forbid, if exist, whether network side network element judges equipment exists urgency traffic; If exist; Then initiate the network side resource release flow, the resource that this subscriber equipment regular traffic is used discharges, and keeps the resource that urgency traffic uses; In the resource that discharges the regular traffic use, whether judges equipment exists signaling bear, if exist, then keeps the signaling bear of subscriber equipment; The network side network element is initiated radio bearer deletion flow process, with discharging the corresponding radio bearer deletion of resource; After urgency traffic finished, subscriber equipment was initiated the urgency traffic termination process on signaling bear.

For the ease of those skilled in the art's understanding, explain below in conjunction with concrete embodiment.

See also Fig. 3; Flow chart for access processing method in the first embodiment of the invention; In the present embodiment, after network side network element (such as mobile management entity MME/Serving GPRS Support Node SGSN) is received tracing section updating request/Routing Area Update request message that user equipment (UE) sends, judge UE in this zone whether business forbid or roam and forbid; If; Then MME/SGSN judges whether UE exists urgency traffic, if do not have, and then tracing section updating request/Routing Area Update request of MME refusal UE; If there is urgency traffic in UE, then MME/SGSN accepts tracing section updating request/Routing Area Update request of UE, and the deleting load-bearing that simultaneously user's regular traffic is used falls, and keeps the relevant bearer that urgency traffic uses, and its concrete implementation procedure is:

1, UE sends and inserts request message to the network side network element; Wherein, for the SAE system, UE sends the tracing section updating request message and gives MME; For the GPRS/UMTS system, UE sends the Routing Area Update request message and gives SGSN.

2, MME or SGSN (follow-up abbreviation MME/SGSN) send location update message to HSS;

Insert subscription data message to MME/SGSN 3.HSS send feedback; Carry the subscription data of UE in the message, comprise the roaming position prohibited area " forbidden location areas for roaming " of UE or position prohibited area " the forbidden location areas for regional provision of service " information of whole feed region;

3 ', said MME/SGSN replys the authorization data acknowledge message to HSS.

4, the HSS home position upgrades acknowledge message to MME/SGSN

5, MME/SGSN is based on user's subscription data and user's access zone, judge UE in this zone whether business forbid or roam and forbid that the situation that possibly exist is:

If UE is not business in this zone to be forbidden or roams and forbid, MME/SGSN normal process then; If UE business in this zone forbids or roams and forbid that then MME/SGSN judges whether UE exists urgency traffic; If UE does not have urgency traffic, the then tracing section updating request of MME/SGSN refusal UE.

If UE business in this zone is forbidden or roamed and forbid, but there is urgency traffic in this UE, then MME/SGSN accepts tracing section updating request/Routing Area Update request of UE.For the SAE system, MME sends the deleting bearing request message and initiates network side load deletion flow process to Serving GW (said Serving GW transmits and delivers to PDN-GW), and the deleting load-bearing that the regular traffic of UE is used falls, and keeps the relevant bearer of urgency traffic use; For the GPRS/UMTS system, SGSN sends deletion PDP Context request message and initiates network side load deletion flow process to Serving GW, and the deleting load-bearing that the regular traffic of UE is used falls, and keeps the relevant bearer of urgency traffic use;

MME/SGSN can judge whether UE exists urgency traffic based on following mode, just judges the emergency bearing whether UE exists urgency traffic to use.Its a kind of judgment mode is: Access Point Name (the Access Point Name that judges the carrying use that UE uses; APN); If find to exist specific APN (said specific APN is the special-purpose urgent Access Point Name of the overall situation just, globally dedicated emergency APN), then MME/SGSN thinks that there is urgency traffic in UE; Another kind of judgment mode is: the urgent indicating bit (Emergency Indication) that uses service quality QoS parameter in the carrying that judgement UE uses; If the value of finding to exist urgent indicating bit is for being, then MME/SGSN thinks that there is the emergency bearing of urgency traffic use in UE, and promptly there is urgency traffic in UE.

When said MME/SGSN keeps the emergency bearing of urgency traffic use, need judge also whether UE exists signaling bear (carrying of a transmitting SIP signaling), if there is signaling bear in UE, then signaling bear also needs to keep.Follow-up urgency traffic finishes back UE need initiate the urgency traffic termination process on signaling bear.For other carrying, then MME/SGSN initiation network side load deletion flow process is deleted these carryings from network.Said MME/SGSN can judge whether carrying is that signaling bear: MME/SGSN judges in the bearer context that UE uses whether have IM CN signaling flag bit (Subsystem signalling flag) according to following mode; If the value of this flag bit is true (True), show that then this carrying is a signaling bear.

5 ', said PDN-GW is to the response of Serving GW feedback deleting bearing, and said Serving GW transmits feedback deletion response to MME/SGSN.

6, MME/SGSN initiates radio bearer deletion flow process, the radio bearer deletion that the carrying of deletion is corresponding;

7, MME/SGSN sends tracing section updating and accepts message to UE;

8, UE replys tracing section updating to MME/SGSN and accomplishes message.

If there is signaling bear, UE initiated the urgency traffic termination process after urgency traffic was accomplished on signaling bear.

See also Fig. 4, be the flow chart of access processing method in the second embodiment of the invention.In the present embodiment; Non-3GPP gateway device is carried out access authentication and authorization flow after receiving the access request that UE sends; Judge whether UE is prohibited from entering in this zone, if then non-3GPP gateway device judges whether UE exists urgency traffic; If no, the access of then non-3GPP gateway device refusal UE; If there is urgency traffic in UE, then non-3GPP gateway device is accepted the access of UE, keeps the tunnel resource that urgency traffic uses simultaneously, and other professional tunnel resource that uses is discharged.Concrete implementation procedure is:

1, UE sends the request of access to non-3GPP gateway device (Non-3GPP GW); For wlan system, non-3GPP Gateway Network Element is EPDG (evolution packet data gateway, Evolved Packet Data Gateway); For the Wimax system, non-3GPP Gateway Network Element is ASN GW (access business network gateway, Access Service Network Gateway); For cdma system, non-3GPP Gateway Network Element is AGW (IAD, Access Gateway).

2, Non-3GPP GW carries out access authentication and authorization flow, judges whether UE allows to insert;

If 3 UE are prohibited from entering in this zone, then Non-3GPP GW judges whether UE exists urgency traffic, if do not exist, and the access of then non-3GPP gateway refusal UE, if there is urgency traffic in UE, then non-3GPP gateway is accepted the access request of UE;

Non-3GPP GW can judge whether UE exists urgency traffic based on following method: Non-3GPP GW judges whether the APN in the employed tunnel of UE exists specific APN (the urgent Access Point Name of overall situation special use just; Globally dedicated emergency APN); If exist, then there is urgency traffic in UE;

4, Non-3GPP GW keeps the tunnel resource that urgency traffic uses, and initiates to discharge tunneled requests to UE, discharges the tunnel resource that regular traffic uses;

4 ', UE feedback tunnel acknowledge message is given Non-3GPP GW;

5, Non-3GPP GW sends the tunnel and removes to connect report message to AAA Server, and notice AAAServer discharges tunnel resource;

5 ', AAA Server replys the tunnel to Non-3GPPGW and goes to report in succession acknowledge message.

In an embodiment of the present invention, the release of resource also can be initiated by UE, and is not just triggered by network side.That is to say, keep resource that urgency traffic uses after the message that the user forbids inserting in this zone and other professional resource of using of start flow deletion if after UE receives to accept message, find to accept to carry in the message.Its concrete implementation procedure sees also figure below.

1, UE sends the tracing section updating request message to MME/SGSN;

2, MME/SGSN receives the tracing section updating request message that UE sends; Judge UE in the zone whether business forbid or roam and forbid if UE forbids inserting, MME/SGSN judges whether UE exists in the urgency traffic in this zone; If there is not urgency traffic in UE; The then tracing section updating request of MME/SGSN refusal UE is sent out the tracing section updating refuse information to UE

If there is urgency traffic in UE, then MME/SGSN accepts the tracing section updating request of UE, sends tracing section updating and accepts message to UE.Tracing section updating is accepted to carry in the message UE and in the zone, is forbidden the information that inserts; Can realize in the following way: accept to increase in the message " Forbidden Access Flag " field at tracing section updating; If the value of this field is True; Show that then UE forbids inserting in this zone,, then show UE normal access in this zone if the value of this field is False;

UE judgement tracking area is followed the tracks of and is accepted the flag in the message; If flag indicates that UE forbids inserting in the zone, then UE keeps the emergency bearing that urgency traffic uses, and judges simultaneously whether UE exists signaling bear; If there is signaling bear in UE, then keep signaling bear;

3, UE replys tracing section updating to MME/SGSN and accomplishes message;

4, UE sends the deexcitation bearing request message to MME/SGSN, initiates the deexcitation flow process, the carrying of deleting other; That is to say that UE judgement tracking area is followed the tracks of acceptance/Routing Area Update and accepted the flag in the message, if flag shows that UE forbids inserting in this zone, then UE keeps the emergency bearing that urgency traffic uses.Judge simultaneously whether UE exists signaling bear (carrying of a transmitting SIP signaling), if there is signaling bear in UE, then signaling bear also needs to keep.For other carrying, then UE initiation deexcitation flow process is deleted these carryings from network;

5, MME/SGSN sends the deleting bearing request message to Serving GW; For the SAE system, MME sends the deleting bearing request message and initiates network side load to Serving GW and delete flow process, and the deleting load-bearing of deexcitation is fallen; For the GPRS/UMTS system, SGSN sends deletion PDP Context request message and initiates network side load to Serving GW and delete flow process, and the deleting load-bearing of deexcitation is fallen;

5 ', Serving GW replys bearing response message to MME/SGSN, the carrying of deletion deexcitation;

6, MME/SGSN initiates radio bearer deletion flow process, and corresponding radio bearer deletion is carried in deexcitation;

7, MME/SGSN sends the deexcitation carrying and accepts message to UE.

If 3 UE are prohibited from entering in the zone, the then access request of Non-3GPP GW refusal UE is sent access-reject message and is given UE; And Non-3GPP GW judges whether UE exists urgency traffic; If exist, then non-3GPP gateway device does not discharge the tunnel resource that UE uses, and waits for the processing of UE;

4, UE receives the access-reject message that Non-3GPP GW sends, and judges whether self exists urgency traffic, if there is no; Then UE discharges the tunnel resource that uses; No longer carry out subsequent treatment, if there is urgency traffic in UE, then UE sends the urgent request message that inserts to Non-3GPP GW; Request is urgent to be inserted, and UE also can insert Access Type in the request message and be set to emergency access and represent urgent access;

5, Non-3GPP GW receives the urgent request that inserts; Send the urgent message that inserts and give UE;

6, UE or non-3GPP gateway device keep the tunnel resource that urgency traffic uses, and initiate the tunnel for other professional tunnel resource that uses and go linker to discharge the tunnel resource that uses;

7 ', non-3GPP gateway device sends the tunnel and removes to connect report message to AAA Server, and the notice tunnel resource is released.AAA Server discharges tunnel resource, goes back to the tunnel then and goes to connect the report acknowledge message to AAA Server.

Need explanation to be; UE also possibly initiate urgent access process under following situation: preserve among the UE and professionally forbid or roam the area information of forbidding; When UE finds to exist in the new preservation prohibited area information of access zone at it and UE have urgency traffic, then UE directly initiates urgent access process and comes access network.Urgent access process is in this case handled the processing among the above embodiment, no longer describes here.

In like manner, the embodiment of the invention provides subscriber equipment need switch or be reoriented to new zone equally.Promptly switching (Handover) or reorientation (Relocation) if source Access Network or source core net find that UE switches or the target area of reorientation forbids inserting to UE in the flow process; Then source Access Network or source core net judge whether UE exists urgency traffic; If exist; Then source is issued and is only comprised the resource information that urgency traffic uses in the resource information of target side; The network of target side is rebuild these resources, and the resource information of other business use will not carried to target side, and these resources are initiated the deexcitation flow process by source and deleted (also can be deleted by UE initiation or target side initiation deexcitation flow process) after accomplishing switching.

See also Figure 11, the flow chart of another access processing method that provides for the embodiment of the invention, said method comprises:

Step S111: when subscriber equipment when the source network switches to the target side network; If the target area of subscriber equipment is a prohibited area; Then the source network judges whether said subscriber equipment exists urgency traffic; If then said source network sends to objective network (step S112) with the resource information that said urgency traffic uses; If not, normal process (step S114)

Step S113: said objective network is set up the resource that urgency traffic uses.

In switching or reorientation flow process; Source Access Network or source core net judges equipment switch or whether the reorientation target area forbids inserting; If then whether source Access Network or source core net judges equipment exist urgency traffic, if exist; Then send RELOCATION REQUEST message, comprise the resource that urgency traffic uses in this message to objective network; Objective network is rebuild the employed resource of urgency traffic, and after these resources were accomplished switching, source network or subscriber equipment or objective network were initiated the deexcitation flow process with these resources deletions.

See also Figure 12 again, eighth embodiment of the invention provides a kind of flow chart of access processing method.In the present embodiment; If source Access Network or source core net find that in reorientation or switching flow UE switches or the target area of reorientation forbids inserting to UE; Then source Access Network or source core net judge whether UE exists urgency traffic; If exist, then in delivering RELOCATION REQUEST message, only carry the resource information that urgency traffic uses, objective network is rebuild these resources after receiving this message.Completion opisthogenesis side joint networks or the source core net is deleted other professional resource of using switching.Its concrete implementation procedure is:

1, the source Access Network is carried out and is switched decision, and whether decision carries out switching.If former connecting system is GPRS, the source Access Network is source BSS; If the source connecting system is UMTS, the source Access Network is source RNC; If the source connecting system is SAE, the source Access Network is source eNodeB; If the source connecting system is Wimax, then the source Access Network is BS (Base Station).Whether the source Access Network is whether whether prohibited area, UE exist urgency traffic to adjudicate to allow to switch according to the target area; Co-exist in following several kinds of situation;

If do not have the prohibited area information of UE in the source Access Network, then source Access Network normal process;

If there is the prohibited area information of UE in the source Access Network, then the source Access Network judge that UE need switch or the target area of reorientation whether in prohibited area, if not in prohibited area, source Access Network normal process then;

If the target area is in prohibited area, then the source Access Network judges whether UE exists urgency traffic, if there is not urgency traffic in UE, then the source Access Network does not allow to carry out and switches, if there is urgency traffic in UE, then the source Access Network allows to carry out and switches;

The source Access Network can use following method, judges whether UE exists urgency traffic, just judges the radio bearer that UE exists:

Judge the APN of the carrying use that UE uses, if find to exist specific APN (globally dedicated emergency APN), then the source Access Network thinks that there is the radio bearer of urgency traffic use in UE, and just there is urgency traffic in UE;

Urgent indicating bit (Emergency Indication) in the qos parameter that the carrying that judgement UE uses is used; If find that having the value of urgent indicating bit is YES; Then the source Access Network thinks that there is the radio bearer of urgency traffic use in UE, and just there is urgency traffic in UE;

2, the source Access Network sends RELOCATION REQUEST message to source core net, carries " resource that needs target side to create " cell in the message, and " resource that needs target side to create " cell can be following dual mode:

The source Access Network only carries the resource information that urgency traffic uses in " resource that needs target side to create " cell in RELOCATION REQUEST message, other professional resource information of using is not carried;

The source Access Network carries all resource informations that UE uses in " resource that needs target side to create " cell in RELOCATION REQUEST message.Handle again by the source core net;

3, the source core net is transmitted and is relocated request-message to the target side core net, comprises " resource that needs target side to create " cell in the message.Whether the source core net is whether prohibited area, UE exist urgency traffic to make decision according to " resource that needs target side to create " cell, the target area that the source Access Network sends; The resource whether decision allows to switch and need target side to create comprises following three kinds of situation altogether:

If the target area is not a prohibited area, then source core net normal process;

If the target area is a prohibited area, and there is not urgency traffic in UE, and then source core net refusal handoff request or re-positioning request are replied handoff failure or reorientation failed message and given the source Access Network;

If the target area is a prohibited area; And there is urgency traffic in UE; Then the source core net allows to switch or the reorientation operation; Transmit RELOCATION REQUEST message, and only carry the resource information that urgency traffic uses in " resource that the needs target side to create " cell in RELOCATION REQUEST message, do not carry other professional resource information of using.The source core net can from " resource that needs target side to create " cell that the source Access Network carries, obtain these information or oneself obtains these information from the carrying that urgency traffic uses; Perhaps carry all resource informations that UE uses in " resource that needs target side to create " cell, accomplish the processing of switching laggard line correlation by target side; Perhaps carry all resource informations that UE uses in " resource that needs target side to create " cell; But carry in the message and indicate that resource that target side core net urgency traffic uses need be created and other resource does not need to create, dual mode processing as follows:

In message, increase and set up indicating bit (Establishment Flag), indicating bit is True, and the pairing resource of expression urgency traffic need be created in target side, and indicating bit is False, and the pairing resource of expression urgency traffic need not created in target side;

In message, increase the cell that resource is set up priority (Establishment Prioritization); This cell value is that the pairing resource of 0 expression urgency traffic does not need to create in target side; Other the pairing resource of value representation urgency traffic needs to create in target side; Be worth greatly more, the priority of the asset creation that expression is corresponding is high more;

4, target core network transmission re-positioning request or handoff request message are given target access network.The information request target side Access Network that carries in " need target side create resource " cell that target core network is carried according to source is set up the corresponding source access network resource of these resources.If target access system is GPRS, target access network is target side BSS; If target access system is UMTS, target access network is a Target RNC; If target access system is SAE, target access network is a target eNode B; If target access system is Wimax, then target access network is target BS (base station, Base Station);

5, the target side Access Network is replied re-positioning request affirmation or switching request acknowledgement message to target side core net;

6, the target side core net is delivered relocation response message to source core net;

7, the source core net is sent reorientation order or switching command message to source Access Network; Increase " Forbidden Access Flag " field in the command messages; If the value of this field is True; Show that then UE forbids inserting in the target area,, show that then UE normally inserts in the target area if the value of this field is False;

8, the source Access Network is sent to UE with reorientation order or switching life message, and notice UE switches;

9, UE switches to the target side connecting system; Transmission handovers complete message to the target side Access Network; If UE finds that " Forbidden Access Flag " is masked as True in the switching command message, then UE only keeps resource that urgency traffic uses and local other professional resource of using that discharges;

10, the target side Access Network sends reorientation and accomplishes message to target side core net;

11, the target side core net is accomplished forwards to source core net with reorientation;

12, target core network is initiated the bearing modification flow process, the resource that the modifying target side is set up;

13, the source core net is received target side core net transmission " delivering re-positioning request " message; If find that UE forbids in the target area inserting; Then the source core net is initiated the deleting load-bearing flow process, keeps the resource that urgency traffic uses, and deletes other professional resource of using.

According to the method that the foregoing description provided, subscriber equipment if subscriber equipment is under an embargo, can be realized the processing of urgency traffic equally in the target area in the process of zone switching or reorientation.

Need explanation to be; Other outer resource deletion of the resource that urgency traffic uses is handled also and can in the access process (like the TAU flow process) that switches after accomplishing, be handled by UE or target side core net; Concrete handling process is described referring to above embodiment, no longer describes here.
